Consider following figure and answer the questions at the end of it.

1.	Consider following figure and answer the questions at the end of it. Figure explains elevation in boiling point when a non-volatile solute is added to a solvent. Variation of vapour pressure with temperature and showing elevation in boiling point. Given that DeltaT_(b) is the elevation in boiling point of the solvent in a solution of molality 'm' then underset(m rarr 0)(Lt) ((Detal T_(b))/(m)) is equal to
Answer» `K_(b)` (MOLAL elevation CONSTANT) `L_(v)` (latent HEAT of vaporization) `Delta S` (ENTROPY change) x (mole fraction of solute) Answer :A
